我想使用pdfVIEwer.jar阅读存储在asset文件夹中的pdf文件,

我试过这种方式,但我收到错误消息,不幸的是它停止了.

谁能帮助我如何实现它.

public class MainActivity extends Activity {@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.activity_main);    copyReadAssets();}private voID copyReadAssets() {    AssetManager assetManager = getAssets();    inputStream in = null;    OutputStream out = null;    file file = new file(getfilesDir(), "ABC.pdf");    try {        in = assetManager.open("ABC.pdf");        out = openfileOutput(file.getname(), Context.MODE_WORLD_READABLE);        copyfile(in, out);        in.close();        in = null;        out.flush();        out.close();        out = null;    } catch (Exception e) {        Log.e("tag", e.getMessage());    }    Intent intent = new Intent(Intent.ACTION_VIEW);    intent.setDataAndType(            Uri.parse("file://" + getfilesDir() + "/ABC.pdf"),            "application/pdf");    startActivity(intent);}private voID copyfile(inputStream in, OutputStream out) throws IOException {    byte[] buffer = new byte[1024];    int read;    while ((read = in.read(buffer)) != -1) {        out.write(buffer, 0, read);    }}}
